A New Method for Locating Feature Points in Pulse Wave Using Wavelet Transform
Xun Zhang, Liyan Xu, Kai‐Jie Chen, Zhengmin Zhou · 2009
This paper aims to propose a new method for positioning pulse signal characteristic point automatically by using embedded software with wavelet transform. Wavelet transform that can provide multi-resolution analysis is a powerful method in pulse signal analysis. By calculating the relative displacement between local maximum which is in high-level detail coefficients of wavelet transform, point e is located more effectively than traditional method. New analysis method for biomedical signal analysis such as pulse signal is put forward.
